Kiltix collar for small dogs, 35 cm is an antiparasitic collar from Bayer (now Elanco) against ixodid ticks, fleas and other external parasites. It's impregnated with two active ingredients: propoxur (1 g per 10 g of collar) and flumethrin (0.225 g). They're released gradually from the collar surface and spread over the dog's skin and coat. According to the manufacturer, protection lasts up to 7 months. The collar is put on at least a day before walks in tick areas and worn constantly.
What it is and who makes it
Kiltix was developed by Bayer and is now made by Elanco. It comes in three sizes: 35 cm for small dogs, 48 cm for medium and 66 cm for large dogs. It's a time-tested product often used as the main protection for the tick season or, on a vet's advice, alongside other products.
Ingredients and action
| Substance | Amount | Action |
|---|---|---|
| Propoxur | 1 g per 10 g of collar | Insecticide against fleas and ticks |
| Flumethrin | 0.225 g per 10 g of collar | Acaricide that boosts action against ticks |
Together they act synergistically: the effect is stronger than either on its own.
How to wear it
- Take the collar out of the pack and stretch it slightly to activate the surface.
- Put it on the dog and fasten it so two fingers fit underneath.
- Cut off the excess, leaving a few centimetres.
- Put it on at least a day before going to tick areas.
- Wear it constantly, including at night.
- Wash your hands after handling the collar.
Pros

- No dates to remember. No monthly treatments needed.
- Three sizes. For small, medium and large dogs.

Cons and what to keep in mind
- Not instant. It takes a day for the ingredients to spread.
- Contraindications. Not recommended for sick or convalescent dogs or nursing bitches.
- Dogs only. This collar isn't suitable for cats.
- Children and play. Don't let children play with the collar or other dogs chew it.
- Not for worms. It doesn't affect internal parasites.
Collar, spot-on or tablets
A collar is convenient because it works for a long time without monthly treatments. Spot-ons last a month and suit dogs that dislike collars. Tablets don't wash off and protect from the first hours, but ticks must attach. To compare another long-acting collar, see our Foresto review. More on choosing in fleas and ticks in dogs.
If you still find a tick
No product gives 100% protection, so check your dog after walks in grass and woods: head, ears, neck, armpits, groin and paws. Remove ticks with a tick hook by twisting, and disinfect the bite. Watch your dog for 2–3 weeks: lethargy, refusing food, fever and dark urine mean an urgent vet visit, as they're signs of babesiosis.
Choosing the size
The 35 cm collar is for small dogs — toy terriers, Chihuahuas, Yorkies, Dachshunds, Pugs and puppies. Medium dogs need the 48 cm collar and large dogs the 66 cm one. Trim the excess after fitting. For lead walks, use a separate regular collar or harness — see how to choose a harness or collar for a dog.
Who it suits
Small dogs that spend a lot of time outdoors, and owners who want season-long protection without monthly treatments. Other products are in parasite control.
Verdict
Kiltix is a proven tick and flea collar with long-lasting protection of up to 7 months. Put it on in advance and keep it on, and still check your dog after walks. It's not recommended for sick or convalescent dogs or nursing bitches.
